I checked my info. at home this weekend and found that my Allens were on my grandfather George Lawrence Davison's side. They were from Conn. and NH. and eventually found their way to Chicago area. My gr grandmother Davison was Hannah Allen her father Augustus Allen and so on. However the cousin I foundsays that her gr mother was Claudia Mae Allen (I thought that she was from TN buit she may have been from ALA. (Of course TN/ALA boundaries are blurred and there has been a lot of line crossing back and forth. FYI and if, you might be interested, my Maury county and associated Pulaski area people were Magills ( an uncle migrated there from Greene CoTN via VA area. My gr gr aunt was Mollie S. Zenor and is buried in MT. Pleasant with her husband John Jacob Ruhm Jr. She died around 1950 and he died around 1945. My mom and some sources said that he and hi sfather Sr. were involved in some of the early phosphate chemical industry in /around Mt. Pleasant/Columbia. I don't think they had any children so that name has died out. The Zenor side come from LA andd MS via KY.and I don't think there are any left in TN.
Sorry I couldn't make the Allen connect but check for Vicki McClintonin on the Magill site. That is where her Allens come from (I think ). It's mprssible they may have migrated from TN and since Maurey and Lawrence are close to the AL line, you might find a connect.
